ʻO ka mākeke Caprolactam i ka hoʻomaka o Iune i ka hihia o ka hōʻemi ʻana o ka lako kūloko a me ka hoʻonui ʻana i ke koi, ua alakaʻi ka nele o ka lako a me ke koi i kahi rebound i nā kumukūʻai mākeke, akā ʻo ka emi ʻana o nā kumukūʻai benzene maʻemaʻe ma uka a me nā kumukūʻai ʻoki PA6 ma lalo, e kaupalena ana i ka hilinaʻi o ka mākeke, ua hoʻoponopono iki ʻia nā kumukūʻai caprolactam.

ʻO ka emi ʻana o ke kumukūʻai o ka benzene maʻemaʻe i hala koke aku nei, ma muli o ka hoʻonui ʻia ʻana o ka lako o ka benzene maʻemaʻe, me ka lako o ke awa ʻo East China e manaʻo ʻia e kau nui ʻia ma ka pou i ka wā ma hope, ka lohi o ke kūʻai ʻana ma lalo, ke kaomi ma ka mākeke benzene maʻemaʻe, ua hāʻule ke kumukūʻai kiko ma ka mākeke East China i 6000 yuan/ton a haʻahaʻa, a hiki i ke kumukūʻai o ka Pōʻahā East China 6100-6170 yuan/ton, ua emi ke kumukūʻai o ka Sinopec benzene maʻemaʻe i 300 yuan/ton a i 6200 yuan/ton. Ua emi ke kumukūʻai o ka benzene maʻemaʻe, a ua loaʻa ka hopena maikaʻi ʻole o ka ʻaoʻao kumukūʻai ma luna o ka caprolactam.

I kēia mau lā iho nei, ua mālama ʻia ka ukana polymerization PA6 ma kahi kokoke i 70%, a ua paʻa ke kūlana hoʻomaka holoʻokoʻa, a hiki i ke koi ma ke kahua milo wikiwiki ke kākoʻo i ka hoʻomaka ʻana o ka polymerization, me kekahi mau mana hana hou a me ka hoʻomaka hou ʻana o ka mana mālama, loaʻa i ka loulou polymerization kekahi kākoʻo no ke koi caprolactam. Eia nō naʻe, me ka emi ʻana o nā kumukūʻai o ka ʻaila maka ma luna a me ka benzene maʻemaʻe, a me ka mana o nā mea maikaʻi ʻole e like me ka lako nui o nā ʻāpana polymer, ke nāwaliwali nei ke kumukūʻai mākeke o nā ʻāpana PA6, ʻoiai ke koi mau nei no nā ʻāpana milo maʻamau, ma lalo o ke kūlana lako nui, ke ulu nei ka waihona o nā hale hana polymerization, aia nō ke kaomi hoʻouna o nā ʻoihana, a ke hāʻule nei ke kumukūʻai.

I kēia manawa, ʻo ke kumukūʻai lako maʻamau o nā ʻāpana milo maʻamau PA6 ma ka mākeke Hikina Kina he 12700-12800 yuan/ton o ke kālā hoʻouna pōkole, ʻoi aku ka haʻahaʻa o ke kumukūʻai o kekahi mau lako ʻākau, a ʻoi aku ke kiʻekiʻe o ke kumukūʻai o kekahi mau ʻāpana ma 12800-12900 yuan/ton, a nāwaliwali ke ʻano kālepa o nā ʻāpana milo maʻamau. ʻO ke kumukūʻai kiko o ka ʻoki semi-optical milo wikiwiki he 13200-13400 yuan/ton i ʻae ʻia, kūʻai nui ʻia ka ʻaelike ʻoki milo wikiwiki, kūʻai maʻamau ʻia ka mākeke ʻoki semi-optical, a ʻoi aku ka maikaʻi o ke koi no ka ʻoki dull.

I ka hōʻuluʻulu manaʻo, ʻoiai he ʻano lako a me ke koi ikaika ka mākeke caprolactam i ka wā e hiki mai ana, ma muli o ka nāwaliwali o nā kumukūʻai huahana o uka a me lalo, e kaupalena ana i ka hilinaʻi kālepa mākeke, ua hāʻule ke kumukūʻai o ka benzene maʻemaʻe o uka, ke kaomi kūʻai aku ʻana o ka hale hana polymerization PA6 iho, ka makaʻala o ke kūʻai ʻana i nā mea maka caprolactam, nā ʻoihana caprolactam e like me kā lākou hana ponoʻī a me ke kūʻai aku ʻana i nā kūʻai kūʻai maʻalahi, ua hāʻule iki kekahi mau kumukūʻai i hala koke nei.

I ke kahua hope, ʻo ka lako caprolactam i ka wā pōkole, ʻo Cangzhou Xuyang phase I overhaul, ua lohi iki ka hoʻolālā hoʻoponopono ʻana o Sanning, ʻo nā ʻoihana ʻē aʻe e hoʻopaʻa i ka hana ʻana, a ʻo ka waihona holoʻokoʻa o caprolactam ma kahi haʻahaʻa, loaʻa i ka ʻaoʻao lako kekahi kākoʻo, a i ʻole e kaupalena i ka pae hoʻoponopono kumukūʻai caprolactam. He nāwaliwali iki ke kumukūʻai a me ke koi, ma muli o ka lohi o ka hana ʻana o ka mana hou a me ka piʻi ʻana o ka waihona awa i manaʻo ʻia, manaʻo ʻia nā kumukūʻai benzene maʻemaʻe e noho manawa pōkole ma kahi o 6000-6200 yuan/ton haʻahaʻa. ʻO nā ʻāpana PA6, ʻoi aku ka nui o nā ʻāpana wili maʻamau, aia ka lako nui, ke piʻi nei nā waihona ʻoihana, a he haʻahaʻa paha nā kumukūʻai huahana. Noho pū nā mea hoʻoikaika o ka mākeke Caprolactam, manaʻo ʻia he paʻa a nāwaliwali ke kumukūʻai pōkole. I ke kahua hope, e hoʻolohe i ka holomua hou o ka mea mālama a me ka loli o ke koi polymerization PA6 ma lalo.
